For the best true drop in, check out R-406A, AKA Autofrost.  True drop in.

There are some long term durability issues with R134, and propane mixtures
tend to leak as the molecule is much smaller.  I did extensive research on this
back in the mid 90's, and Autofrost was one of the better R12 retrofits.
